9 - VENTING
Use Table 9R.2 for reference on CFM replacement air if drawing intake air from inside the house and open air requirements
for intake screen/vent or consult Hearth & Home Technologies for more information.
Recommended to prop the fireplace up off the floor at least 2.5".
You have to make sure there is 78 sq. inch of area in a pathway, intake grill, toe-kick breather, etc. to get under the fireplace.
WARNING! Risk of Fire!
DO NOT
draw intake air from an attic or crawl space. Appliance could overheat.
This fireplace has the options of air intake connections on the side or the bottom of the fireplace.
The collar is not shipped in place. See assembly instructions below.
This fireplace is approved for use with 10 inch rigid metal pipe or UL approved 10 inch Class 0 or Class 1 flex for intake air.
Use Table 9R.1 for venting requirements if using UL approved 10 inch flex for intake air.
Vent runs utilizing 10 inch rigid metal pipe may be 110 feet with 11 elbows. We recommend insulating the intake air duct or using UL
approved Class 1 insulated flex in hot, humid or cold climates.
The intake pipe must maintain 1.5X the square inches of the flue pipe in free area. Intake screen/vent must be sized appropriately.
Failure to do so will result in higher operating temperatures.
The fireplace may also take room air for combustion. Intake screen/vent must be sized appropriately. You must plan for the replacement
air that is consumed from the room by the fireplace. Do not draw intake air from a crawl space or an attic (ventilated or not ventilated).
